So these guys have to read up on some articles about multisided marketplaces which what they were testing. Starting a matching platform between consumers and teachers is not a feasible plan because this is a longer term relationship and a platform is easily cut out. A platform like uber works because nobody has a regular cab driver. Supply and demand matching is also terrible for dog walking platforms. Don't spend time testing all kind of startup ideas with complicated technique when you don't know what multisided marketplaces are and network effects.
